Also ntpdate seems to have been deprecated in the last few years...it disappeared after Ubuntu 6.06LTS. The FreeBSD 7.x manpage lists it in a state of mourning, being replaced by ntpd -q [but the Linux ntpd does not list -q as an option].

Definitely WiFi instead of [or at least in addition to] the wired ethernet. For now I'll be using a lot of plugged-in USB devices and that's okay in a development world, but for the end users, they should be able to just plug it in the wall and use it.
